How to get a variable's System Data Type.
I need to find all the variables that are of type, System.IO.StreamReader, using fxcop. How do i achieve this.
If not possible do let me know the reason.
It would be helpful if some sample code would be available.

Hi Venkatesaperumal
Depends what variable you're talking about. For fields on classes, you can do the following:
TypeNode m_streamReader;
public override void BeforeAnalysis()
{
m_streamReader = FrameworkAssemblies.Mscorlib.GetType(Identifier.For("System.IO", Identifier.For("StreamReader"));
}
public ProblemCollection override Check(Member member)
{
Field field = member as Field;
if (field == null) return null;
if (field.Type.IsAssignableTo(m_streamReader))
{
//do rest of your analysis
}
}
If you're looking for local variables (inside the method) modify the code slightly:
TypeNode m_streamReader;
public override void BeforeAnalysis()
{
m_streamReader = FrameworkAssemblies.Mscorlib.GetType(Identifier.For("System.IO", Identifier.For("StreamReader"));
}
public ProblemCollection override Check(Member member)
{
Method method = member as Method;
if (method == null) return null;
LocalList locals = Method.Instructions[0] as LocalList;
if (locals == null) return null;
foreach(Local local in locals)
{
if (loacl.Type.IsAssignableTo(m_streamReader))
{
//do rest of your analysis
}
}
}
